Investigate the profile recovery feature

[Solanya]

Back when chat links were implemented, profile chat links had the option to import it to help recover a profile if it was lost after data loss but still present in someone else's directory. I'm unsure if this feature ever worked properly, but it currently doesn't for a couple of reasons:

• A check was added to ensure the player importing the profile actually made the profile (to avoid facilitating impersonation). However, that check was incorrect and checks the sender instead of the receiver.
• The profile that would be sent would have the structure of a profile stored in the directory instead of a profile of your own. The structure has differences which will cause Lua errors if copied strictly, so it needs to be converted upon import.

It would be good to see if both of these issues could be fixed to make it possible to retrieve your profiles from someone else easily.
